Abstract
The charged particles produced in the O18+C12 reaction at 16.7 MeV/nucleon have been detected using the GARFIELD+RCo apparatus at Laboratori Nazionali di Legnaro and compared with the transport code antisymmetrized molecular dynamics (AMD) followed by gemini++ as afterburner. To our knowledge, it is the first time that this model is applied to a nuclear reaction between light nuclei at so relatively low bombarding energy. The general agreement between experimental data and model is very good for fragments with Z≥10, assuming a fusion process source, and for intermediate fragments (Z=3,4). A discrepancy in the relative cross section of the different reaction mechanisms has been pointed out for fragments with 4<10 as the model seems to produce less dissipative reactions.
